I think the problem with that, Kestrel, is that those results wouldn't have any statistical weight. With something this contested, really rigorous studies are going to be needed to convince the general public. Unfortunately, if they can't "scientifically" verify the length of time on the diet and the type of foods eaten, saying you've been on the diet for 30 years is pretty much anecdotal evidence. Too bad, but they're definitely making headway towards providing strong supporting evidence for what we all know about -- the crazy, amazing health benefits of LC!
